UNITED STATES PATENT OEErcEO ALVA O. DOVNEY, OF SPRING LIOK, ASSIGNOR OF ON E-HALF TO N. C. TILFORD, OF OANEYVILLE, KENTUCKY.

HARROW.

SPECIFICATION forming part of Letters Patent No. 389,138, dated September 4, 1888. I `Application filed April 4, 1888. Serial No. 260,559. (No model.)

To all whom z'z may concern:

Be it knownthat I, Amit C. DowNEY, a citizen of the United States, residing at Spring Liek,in the county of Grayson and State of Kentucky, have invented certain new and useful Improvements in Harrows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a combined disk and scratch-tooth harrow.

The purpose of the invention is the provis ion of a harrow that will cut through stubble, clods, and weeds, and which will present an extended surface, and be composed of two halves pivoted together, the Vfront half being supported on cutter-disks that have a swivelconnection with the frame, so that the said cutter-disks can adapt themselves to the draft of the harrow, and will at the same time form rolling supports that will facilitate the turning of the harrow at each end of a row or whenever desired.

The improvement consists in having the frame composed of two halves,which are pivotally connected together, and in having the front half of the frame mounted ou cuttingdisks that have the Shanks ot' their supports connected by a swivel-joint with the frame, and in having the rear half ot' the frame provided with scratch-teeth,which are secured to pivoted toothbars, so that the angle of the teeth can be varied at will.

The improvement further consists of the novel features which hereinafter will be more fully described and claimed, and shown in the annexed drawings, in which- Figure l is a perspective View of my harrow; and Fig. 2,a side View, parts being broken away, of the harrow, showing the adjustment of the scratelrteeth by dotted lines.

Theharrow-frame is composed of the two parts or halves A and B, that are pivoted together by the rivets or bolts e. The front half, A, of the frame is provided with the cuttingdisks C, which are journaled in frames D, that have their shanks passed through openings in the cross-bars of the frame and journaied in the said cross-bars, so that the cutting-disks can swing around and adapt themselves to the draft of the harrow. The rear half, B, of the frame is provided with the scratch-teeth E, that are secured in the toothbars c,which are journaled at their ends in the side beams of the said half of the frame, forming a pivotal connection between the said tooth-bars c and the half of the frame, so that the teeth can be set at any angle or slant. The eyebolts F are inserted in the pivoted tooth-bars c from their under side and are connected with the hand-lever G by the connection f. Each bar E is provided with an eyebolt near each end, and the connection f connects the eyebolts of the bars and is attached to the hand-lever, so that all the tooth bars can be adjusted simultaneously. The hand-1ever G is pivoted to the draft-beam H, and is adapted to engage with the notches ot' the segment 7ir to hold it in an adjusted position.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s-

1. Theliereinspecilied harrow,eomposedof the frame consisting of a front and rear halt, the two halves being pivotally connected together and having the front hall' of the frame mounted on cutting-disks, which have a swivelconnection therewith, and having the rear half ol' the frame provided with scratching-teeth, substantially as described.

2. The eombinatiomwith the narrow-frame made in two parts, which are pivoted together, ofthe cutting-disks supporting the front half ofthe frame and having a swivel'connection therewith, the tooth-burs pivotally connected with the rear frame and having scratching teeth,the eyebolts,the lever and segment, and the connection between the eycbolts and the said lever, substantially as and for the purpose described.

In testimony whereof` I affix my signature in presence of two witnesses.
